MM88C29 • MM88C30
Quad Single-Ended Line Driver •
Dual Differential Line Driver
General Description
The MM88C30 is a dual differential line driver that also per-
forms the dual four-input NAND or dual four-input AND
function. The absence of a clamp diode to V
CC
in the input
protection circuitry of the MM88C30 allows a CMOS user to
interface systems operating at different voltage levels.
Thus, a CMOS digital signal source can operate at a V
CC
voltage greater than the V
CC
voltage of the MM88C30 line
driver. The differential output of the MM88C30 eliminates
ground-loop errors.
The MM88C29 is a non-inverting single-wire transmission
line driver. Since the output ON resistance is a low 20
Ω
typ., the device can be used to drive lamps, relays, sole-
noids, and clock lines, besides driving data lines.

Note 1:
“Absolute Maximum Ratings” are those values beyond which the
safety of the device cannot be guaranteed. Except for “Operating Tempera-
ture Range” they are not meant to imply that the devices should be oper-
ated at these limits. The Electrical Characteristics tables provide conditions
for actual device operation.
Note 2:
AC Parameters are guaranteed by DC correlated testing.

Typical Data Rate vs Transmission Line Length
Note:
The transmission line used was #22 gauge unshielded twisted pair
(40k termination).
Note:
The curves generated assume that both drivers are driving equal
lines, and that the maximum power is 500 mW/package.
